Low-poly style image and video processing

Low-poly has lately become a trending style in flat designs, Web designs, illustrations, and etc., in which only a small amount of triangles are used to provide an abstract and artistic effect. However, creating designs in low-poly style manually is obviously a tiring job. In this paper, we propose a real-time triangulation method to synthesize images and videos automatically into low-poly style. In order to keep edge and color information out of limited triangles, vertices on the edges detected in the image have a greater probability to be selected to compose triangles. For video low-poly stylization, an anti-jittering method is proposed to eliminate the abrupt changes in position and color of the triangles between adjacent frames. We use OpenGL Shading Language (GLSL) to speed up the calculation in GPU. We compare images generated with our method with other algorithms and those drawn manually by artists. Results show that our method provides an elegant and artistic effect for low-poly in real-time.
